Cat water pump bearing

Normally I would bow to Wolfe's professional knowledge. But the Cat C7 in a rear engine MH does have some problems that C7's do not have in other applications. That bearing is one of them. I am convinced that it is due to a heat retention in that area. I have read Fire Fighter forums and do not ever remember seeing that problem with the C7. Some RV owners have even posted the part #'s for changing over to a greasable bearing. I have also noticed that it is rare to see someone posting about the bearing disintegrating in a Pre C7 Cat ( greasable). When we had a MH with a C7 I carried a spare bearing! Never had to use it as we sold that unit within 12 months.
